India, Aug. 1 -- A lightning flash in a notorious storm hotspot in the United States nearly a decade ago has been certified as the longest on record.

An incredible 829 kilometers long (515 miles) megaflash occurred during a major storm in the Great Plains in October 2017 and was 61 kilometers greater than the previous record, also set in the same region.

It extended from eastern Texas to near Kansas City, equivalent to the distance between Paris and Venice in Europe: a journey that would take roughly eight to nine hours by car, or at least 90 minutes by plane.

The flash was not identified in the original 2017 analysis of the storm but was discovered through re-examination, the World Meteorological Organization announced on Thursday.?
